Aegilops triuncialis

Common names: barb goatgrass, barbed goatgrass
Aegilops triuncialis (barb goatgrass) is an annual grass (family Poaceae) that grows in rangelands, grasslands, and oak woodlands. It is becoming a dominant grass in foothill grasslands of central California. This weed can directly injure livestock by lodging in their eyes or mouths, and is unpalatable to cattle. It is native to many areas in Eastern and Mediterranean Europe and Western Asia.
